Mr. Maxwell bought new basketball shows with the discount shown. He has a $10-off coupon he can use after the percentage off. If Mr. Maxwell bought the shows for $61.25, what was the original price?

A. If the shoes are discounted 25%, what percent of the original price is the original price?

25% discount is the same as □□% of the original price.

B. Fill in the boxes to set up the equation to find the original price of the shoes.

□□% ⋅⋅ Original Price −=61.25−=61.25

C. What would be the price without a $10-off coupon?

61.25+□=□61.25+□=□ $_____
